  • Clamping device that develops both axial and circumferential clamping forces in response to a common axial clamping force
    Patent number: 11077519
    Abstract: Clamping devices and associated methods that are useful to develop both axial and circumferential clamping forces in response to a common axial clamping force. The clamp is able to use a simple mechanism to generate both kinds of clamping forces from a single, axial actuating force. The clamping devices of the present invention are particularly useful for clamping cover and base deck components of a hard disk drive enclosure together to allow the components to be joined and sealed together using welding techniques.
